Problems solved by technology

At present, the optical light distribution of LED light sources on the market is mainly realized by LED lenses. The commonly used transparent LEDs are mostly circular lenses with rotational symmetry, which can form a uniform circular light spot on the illuminated surface. However, if this Circular symmetrical light distribution is used in non-completely symmetrical three-dimensional spaces such as corners, roads or narrow alley edges, which will not only cause a great waste of LED light energy, but also bring light pollution to the surrounding environment

Abstract

The invention provides a trimming structure, which comprises a base plate assembly and a plurality of lens modules arranged on the base plate assembly, wherein the base plate assembly is a folding line type base plate and comprises a plurality of sequentially connected base plates, in addition, a preset included angle exists between the located planes of any two adjacent base plates, each lens module comprises a plurality of lenses, the lenses of each lens module are arranged on the corresponding base plate, and in addition, the emitted light rays are subjected to secondary trimming processing. The invention also provides an LED (light emitting diode) lamp adopting the trimming structure. The trimming structure can form the trimming distribution similar to the trimming angle of the lens and the narrow and long type trimming distribution on illuminated surfaces, further, narrow and long type light spots with uniform illumination intensity are formed on the illuminated surfaces, and the trimming requirements of the LED lamp are met.

Description

technical field [0001] The present invention relates to the lighting field, in particular to a light distribution structure and an LED (light emitting diode, light-emitting diode) lamp applying the light distribution structure. Background technique [0002] As a semiconductor device that can convert electrical energy into light energy, LED is widely used in various lighting fixtures due to its advantages of high efficiency, low energy consumption and long life. These lamps have become indispensable in people's life and work. Lighting appliances. However, since LED itself is a Lambertian light source, its luminous intensity is mostly lower on both sides and higher at the center, so LED generally cannot be directly applied to the lighting field. Therefore, it is particularly important to perform optical light distribution on LED light sources. At present, the optical light distribution of LED light sources on the market is mainly realized by LED lenses. The commonly used tra...
